Summary: US CPI up in February; in line with expectations; “core” rate also up but less than expected; “nothing for inflationistas” to sound inflation alarm; headline rate driven by higher fuel prices; “base effects” to prompt higher annual inflation rates from March
The annual rate of US inflation as measured by changes in the consumer price index (CPI) halved from nearly 3% in the period from July 2018 to February 2019. It then fluctuated in a range from 1.5% to 2.0% through 2019 before rising above 2.0% in the final months of that year. Substantially lower rates were reported from March 2020 to May 2020 but subsequent reports indicated consumer inflation has largely returned to pre-pandemic levels.
The latest CPI figures released by the Bureau of Labor Statistics indicated seasonally-adjusted consumer prices rose by 0.4% on average in February. The result was in line with the generally expected figure and higher than January’s 0.3% increase. On a 12-month basis, the inflation rate accelerated from January’s reading of 1.4% to 1.7%.

“Headline” inflation is known to be volatile and so references are often made to “core” inflation for analytical purposes. Core inflation, a measure of inflation which strips out the volatile food and energy components of the index, increased by just 0.1% on a seasonally-adjusted basis for the month. The result was less than the expected 0.2% but higher than January’s 0.1% increase. The annual rate slipped for a second consecutive month, this time from 1.4% to 1.3%.
NAB currency strategist Rodrigo Catril said “there is nothing for the inflationistas to ring the alarm while at the same time it provides the Fed plenty of breathing space ahead its meeting next week.”
US Treasury bond yields barely moved on the day. By the close of business, the 2-year yield remained unchanged at 0.16%, the 10-year yield had slipped 1bp to 1.52% and the 30-year yield finished unchanged at 2.24%.
In terms of US Fed policy, expectations of any change in the federal funds range over the next 12 months remained fairly soft. March 2022 futures contracts implied an effective federal funds rate of 0.095%, just above the spot rate.
The largest influence on headline results is often the change in fuel prices. In February, “motor fuel” increased by 6.4% on a seasonally adjusted basis, adding nearly 0.2% to the total change for the month. “Shelter” costs increased by 0.2%, adding around 0.07% to the overall increase. Commodity prices excluding food and energy fell by 0.2%, subtracting 0.04% from the index.
